The current situation is that FreeBSD uses a port of LinuxThreads to provide support for kernel threads. (The older native pthread library is userland-only.) FreeBSD also supports LinuxThreads for Linux emulation - it'll run StarOffice 5. (Instead of clone(), FreeBSD has the rfork() system call.)
The plan for the future is to have a combination userland/kernel threading library to reduce the cost of context switches between threads.
